The embodiment of the present disclosure provides a kind of method of reporting buffer status report, can be used for terminal, comprising the following steps:
In a step 101, it after reporting target cache state report BSR to base station, determines whether to meet the trigger condition for reporting the target BSR again；
In a step 102, when meeting the trigger condition, report the target BSR to the base station again.
In above-described embodiment, terminal can be after reporting target BSR to base station, it determines whether to meet the trigger condition for reporting target BSR again, and when meeting the trigger condition, report the target BSR to base station again, so that base station can be terminal distribution ascending resource according to target BSR in time, it is ensured that the transmission speed and quality of the upstream data of terminal.
For above-mentioned steps 101, in the embodiment of the present disclosure, target BSR can be conventional BSR or filling BSR.
According to the relevant technologies, the terminal can report conventional BSR to base station when uplink buffer area is sky and has new data to be sent to reach.That is, all logic channels in all logic channel groups without transmissible upstream data when, if any one logic channel for belonging to any one logic channel group at this time has data transmittable, terminal can report conventional BSR.For example, the process for sending routine BSR to base station can be triggered when terminal sends upstream data to base station for the first time.
Alternatively, the terminal reports conventional BSR to base station when the data to be sent for currently having high priority reach.That is, waiting the uplink scheduling authorization of base station transmission if terminal has had sent BSR.There are the data of higher priority to need to transmit at this time, then terminal can report conventional BSR to base station.Wherein, the priority of logic channel belonging to the data of higher priority is higher than the priority of the logic channel in any one logic channel group.
Filling BSR is that the ascending resource of the upstream data base station distribution sent for this is more, and some fillers do not need transmission data, these fillers can be used at this time to carry out the transmission of BSR, the BSR sent using these fillers is exactly to fill BSR.
After terminal reports the target BSR to base station, base station can be terminal distribution ascending resource according to target BSR according to the relevant technologies, can carry out the transmission of upstream data after terminal acquisition ascending resource on the ascending resource.
At this point, whether terminal can detecte currently meets the trigger condition for reporting target BSR again.
First the concept that the embodiment of the present disclosure is related to is illustrated below.
The first logic channel in the embodiment of the present disclosure can be any one logic channel, or in order to save the expense of BSR, first logic channel can be defined as to current all there are the logic channels of highest priority in the logic channel of data to be sent, the i.e. logic channel of highest priority.
Second logic channel is logic channel of the priority lower than the priority of target logic channel, that is to say, that the second logic channel is the lower logic channel of priority.Wherein, the target logic channel is the logic channel for the caching that currently exist for carries out data transmission.
Logic channel group in the embodiment of the present disclosure is any one the logic channel group for including multiple logic channels.Or, equally for the purpose for the expense for saving BSR, logic channel group can be defined as include the logic channel of highest priority logic channel group, that is to say, that all there are the logic channel groups of the logic channel of highest priority in the logic channel of data to be sent including current.
Data to be sent for history can be distinguished according to the successive of queuing time, and the forward history of queuing time data to be sent are as the first history data to be sent, and the history of queuing time rearward data to be sent are as the second history data to be sent, etc..
It for new data to be sent, then can equally be distinguished according to the sequencing of arrival time, arrival time is the first new data, followed by the second new data, third new data, the 4th new data, etc. near preceding data.
Based on above-mentioned definition, in the embodiments of the present disclosure, optionally, trigger condition includes any one of following:
The first situation when the first logic channel, logic channel group or terminal data to be sent there are the first history, has the first new data to be sent to reach, and the data volume of first new data reaches the first preset value.
First logic channel, logic channel group or the terminal are after having reported target BSR, if there is also the first history data to be sent, and there is the first new data to be sent to reach, and the data volume of first new data reaches the first preset value, then illustrates that the new data currently reached is more.If latent period BSR report the ascending resource that can just get base station distribution if, terminal side can be made to have a large amount of newly arrived data to be in etc. in state to be sent, influence the transmission speed and quality of upstream data.Therefore, in the embodiment of the present disclosure, the trigger condition for meeting and reporting target BSR again can be determined at this moment.
In the embodiment of the present disclosure, it shall be noted that ground is that above-mentioned first logic channel, logic channel group and the terminal can be counted according to different buffer data size sizes.That is, the first logic channel, logic channel group and corresponding first preset value of terminal can be different numerical values recited.For example, the first logic channel reaches the first preset value A in the data volume of the first new data1When, determination meets the trigger condition；And logic channel group then reaches the first preset value A in the data volume of the first new data2When, determination meets the trigger condition；Terminal then reaches the first preset value A in the data volume of the first new data3When, determination meets trigger condition, wherein A1<A2<A3。
If there are the first history data to be sent in each logic channel or each logic channel group, and there is the first new data to be sent to reach, and the data volume of first new data is when reaching the first preset value, determination meets the trigger condition, and report target BSR to base station, the expense of BSR can be made larger.
In the embodiment of the present disclosure, optionally, it can be that current all there are when the logic channel of highest priority in the logic channel of data to be sent in the first logic channel, that is, when the first logic channel is the logic channel of highest priority, if there are the first history data to be sent for first logic channel, and there is the first new data to be sent to reach, and the data volume of first new data, when reaching the first preset value, just determination meets the trigger condition, to save the expense of BSR.
Similarly, it can also include first logic channel in the logic channel group, when including the logic channel of highest priority in the i.e. described logic channel group, if there are the first history data to be sent for logic channel group, and there is the first new data to be sent to reach, and the data volume of first new data reaches the first preset value, just determination meets the trigger condition, equally saves the expense of BSR.
In addition, in this case, it can also be when the arrival duration of first new data in the first logic channel, logic channel group or the terminal reaches preset duration, just determination meets the trigger condition.That is, in the first logic channel, logic channel group or the terminal, there are the first history data to be sent, and there is the arrival of the first new data, when the data volume of the first new data reached is larger and arrival duration is longer, just determination meets the trigger condition, determine to meet at this time reports target BSR to the trigger condition of base station again, further saves the expense of BSR.
Second situation, the first logic channel, logic channel group or the terminal have the arrival of the second new data, and the arrival duration of second new data reaches preset duration.
First logic channel, logic channel group or the terminal are after having reported target BSR, if there is the arrival of the second new data again, and the arrival duration of second new data reaches preset duration, then illustrate that the second new data has arrived at the long period, if latent period BSR report can just get base station distribution ascending resource if, meeting influences the transmission speed and quality of upstream data so that the second new data waiting time of terminal side is longer.Therefore, In the embodiment of the present disclosure, the trigger condition for meeting and reporting target BSR again can be determined at this moment.
Optionally, the first logic channel, logic channel group and the corresponding preset duration of terminal can be different duration.For example, the first logic channel, logic channel group and terminal reach preset duration T in the arrival duration of the second new data respectively1、T2And T3When, determination meets the trigger condition.Wherein, T3Value can be maximum, T1Value can be minimum.
In addition, in this case, in order to save the expense of BSR, it equally can be when the first logic channel be the logic channel of highest priority or logic channel group includes the logic channel of highest priority, if there is the second new data to be sent reaches, and the arrival duration of second new data reaches preset duration, just determination meets the trigger condition.
The third situation, there are the second history data to be sent for the first logic channel, logic channel group or the terminal, and have third new data to be sent to reach, wherein the data volume of the second history data to be sent is lower than the second preset value.
First logic channel, logic channel group or the terminal are after having reported target BSR, there are the second history data to be sent, and when thering is third new data to be sent to reach, if the data volume of the second history data to be sent is lower than the second preset value, according to the relevant technologies latent period BSR report can just get base station distribution ascending resource if, then the transmission of the second history data to be sent can not be rapidly completed.Therefore, in the embodiment of the present disclosure, the trigger condition for meeting and reporting target BSR again can be determined at this moment.
Optionally, the first logic channel, logic channel group and corresponding second preset value of terminal are also possible to different numerical values reciteds.For example, the first logic channel, logic channel group and terminal can be respectively the second preset value B in the data volume of existing second history data to be sent1、B2And B3When, determination meets the trigger condition wherein, B3Value can be maximum, B1Value can be minimum.
In addition, in this case, in order to save the expense of BSR, it equally can be when the first logic channel be the logic channel of highest priority or logic channel group includes the logic channel of highest priority, if there is the second history data to be sent, and there is third new data to be sent to reach, wherein, the data volume of the second history data to be sent is lower than the second preset value, and just determination meets the trigger condition.
Optionally, in this case, can also be when the arrival duration of the third new data in the first logic channel, logic channel group or the terminal reach preset duration, just determination meets the trigger condition.That is, in the first logic channel, logic channel group or the terminal, there are the second history data to be sent, and have third new data arrival, the data volume of the second history data to be sent it is less and reach third new data arrival duration it is longer when, Determination meets the trigger condition, to need to report target BSR to base station again.Further save the expense of BSR.
4th kind of situation, the corresponding buffer area of the second logic channel are empty and have the 4th new data to be sent to reach；The priority of second logic channel is lower than the priority of target logic channel, and the target logic channel is the logic channel for the caching that currently exist for carries out data transmission.
In such cases, the second logic channel is logic channel of the priority lower than the priority of target logic channel, that is to say, that the priority of the second logic channel is lower.And the second logic channel is after having reported target BSR, if corresponding buffer area is empty and has the 4th new data to be sent to reach, it can not be triggered according to the relevant technologies and report conventional BSR, need reporting for latent period BSR that can just get corresponding ascending resource.In the embodiment of the present disclosure, in order to improve the transmission speed and quality of upstream data, the trigger condition for meeting and reporting target BSR again can be determined at this moment.
5th kind of situation, detects and service quality stream is remapped to the second Deta bearer by the first Deta bearer in service data adaptation layer；Wherein, first Deta bearer and second Deta bearer correspond to different logic channel groups.
Base station the reasons such as needs according to current ink, RRC (Radio Resource Control can be passed through, wireless heterogeneous networks) message, in SDAP (service data adaptation protocol, service data adaptation) some service quality stream is remapped on the 2nd DRB by layer by the first DRB (Data Radio Bearer, Deta bearer).If the first DRB and the 2nd DRB corresponds to different logic channel groups, the caching situation of terminal can change, accordingly, it is desirable to which base station re-starts adjustment to ascending resource.Therefore, in the embodiment of the present disclosure, the trigger condition for meeting and reporting target BSR again can be determined at this moment.
In this case, optionally, lower layer PDCP (Packet Data Convergence Protocol can also be not issued at SDAP layers in the data buffer storage of the service quality stream, data packet convergence protocol) layer when, determination meets the trigger condition, has equally achieved the purpose that save BSR expense.
In the embodiment of the present disclosure, it can determine that determining satisfaction reports the target BSR trigger condition again when meeting above situation.To continue to execute step 102.
For above-mentioned steps 102, terminal can report target BSR to base station again according to the relevant technologies.The target BSR can be conventional BSR or filling BSR.
It wherein, can include routine BSR in MAC (Media Access Control, the media access control) PDU (Protocol Data Unit, protocol Data Unit) for being sent to base station when target BSR is routine BSR MAC CE (Control Element, control element), to realize the purpose for reporting conventional BSR to base station.
When target BSR is filling BSR, it can be after the ascending resource for the base station distribution that terminal receives, the purpose that filling BSR is reported to base station is realized by including the MAC CE of filling BSR in MAC PDU comprising filling BSR in being not used in data corresponding to the filler that carries out data transmission.
Base station can distribute in time ascending resource to terminal, so that terminal sends upstream data after receiving target BSR according to the relevant technologies.
In the embodiments of the present disclosure, if after meeting trigger condition and having reported target BSR to base station again, whether also terminal can still continue to test meets the trigger condition, and when determination meets the trigger condition again, report target BSR to base station again, so that base station can be terminal distribution ascending resource according to target BSR in time, it is ensured that the transmission speed and quality of the upstream data of terminal.
